RISC-V: Remove unused class definitions

Removes a whole lot of unnecessary boilerplate code. Machines
don't need to be objects. The expansion of the SOC object model
for the RISC-V machines will happen in the future as SiFive
plans to add their FE310 and FU540 SOCs to QEMU. However, it
seems that this present boilerplate is complete unnecessary.
